The relay "62 will thus be deen'erg'ized, releasing itscontrol of the contacts 63 and 64, resulting in the opening of the starting circuit, closing or the resetting circuit and the provision 'of a new, ground for the circuit controlling the relay 65, this circuit being traced from the grounded? battery 68 through the winding of the relay contact 14;.the

that is} until the contacts lfl and 19 have been disposedadjacent their respective terminals and a the apparatus released to bringthem in intimate.

engagement with the terminals, the test set has a V hadsufficient timetobe reset. In releasing the apparatus the switch members 42 and 44 move from the position shown in Fig. 9 tothe position shown in Fig.8, where therelay 62-will be energized, as shown in Fig.6, through'the switch members 42 and 44 to' ground 41, conditioning the control circuit forfthe energization of the e relay 65 when the opposing members ofthe apparatus come to rest (Figs. 1, 2 and 7) with their contactsin intimate engagement with the terminals of the terminal strip and theiswitch memberi i a 42 positioned between and out of engagement with theportions of the switch member 44. The. energization of'the relay 62 at this position with the complete connections of the "electrical structure to be tested have been made with the proper electrical circuits ofthetest set to open the resetting circuit and close the starting circuit so that the testing operation may begin.

. In the operation of the apparatus it will be observed, by viewing Figs 1 and 2, that the terminals 52 and, 53 are electrically connected to i electrical units 59 to betested. Each terminal 9 '52 iselectrically. connected'to its' respective ter e .minal 22v and in the sajmemanner each terminal.v

' V 53 is electrically connected toits respective terminal 23. Therefore when the contacts I8 and. a 190i the apparatus are electrically connected to a test set it is possibleto electrically connect each unit to be tested thereto by connecting the appa' i ratus to the terminals 22 and 23 of the terminal the a teen wi t t n se ehtiw th theirlterminalsfig. When1 this hasbeen accorn plished theeleotricalunits to be' tested are .e1ec

tricallyicormected tothetest setj. During this relative movement of the opposing members Ill andl I the switch members 42 and 44 are moved relativeto each other from the positionshown .in Fig.5 and through thesuccessiveipositions shown in Figs. 6, 7,]8, 9, 8 and '7. These switch members, therefore, control the two circuits of the test set 56, namely the starting circuit 60 and the resetting circuit 6|. .The switch members 42. e

and are; therefore, constructed and arranged so" that the-necessary relativemovement of the P opposing members In and II will cause thejrconpresence of oxidation on the terminals or other incidents which might arise, wherein a defectin one or more of the electrical units under test is registered on the test set, the operator may wish' to repeat the-test on the units. In any case, all

, the operator need do is actuate the apparatus,

that is cause. movementcofithe member I rela- '-tiveto the member ll and release themember II! "in an effort to (get a more positive electrical connection between the contacts and the terminals to be sure that the lack of a good elec-L 'trical connectionatthiS point is not, the cause the contacts l8 and 19 causes a wiping action on their terminals to assure positive connections.
